Abstract
The invention includes a spraying device ( ) for producing a precise degree of liquid droplet generation on a repeatable basis by combining a specified rate of regulated flow of liquid material with a regulated flow of high-pressure air. The spraying device ( ) includes an electric or engine driven direct drive compressor ( .) Coupled to the compressor ( ) is an air storage tank ( ) providing air pulsation reduction to the regulated air and serves as a reservoir for excess airflow generation. A Venturi nozzle ( ) is connected to the compressor ( .) A liquid supply tube ( ) uses a fixed or variable restriction to regulate the liquid flow to the nozzle ( .) The vacuum in the liquid supply line ( ) draws this liquid flow and mixes the liquid externally with the regulated air in exacting proportions forming specified liquid droplet sizes. The device ( ) uses air and liquid regulation combined with a Venturi nozzle ( ) and is able to generate extremely consistent liquid droplet sizes.
